Analysis: Wrong. How much sebum sebaceous glands can produce is mainly determined by heredity, which changes with the change of androgen level in the body, showing that the oil output decreases with age. In addition, good rest and eating habits also help to reduce greasy situations.
Analysis: Wrong. Too low frequency of shampooing will cause dirt and microorganisms to gather on the scalp, which will naturally cause various scalp problems. However, under the normal shampoo frequency, scalp itching may still occur. At this time, this is a stimulating reaction caused by fungi, not insufficient cleaning. Dandruff shampoo should be considered. If there is seasonal itching, it may also be an individual susceptibility problem. Pay attention to relieve anxiety and keep relaxed.
Analysis: Wrong. Grasping nails can cause scalp injury, which in turn leads to infection, making scalp problems more and more serious, and may also lead to hair loss due to pulling. When using anti-dandruff shampoo products, the correct shampoo method is: first, knead rich shampoo foam in the palm, and then massage the scalp moderately with the fingertips to achieve full cleaning and anti-dandruff effect.
Analysis: Wrong. Hair conditioner without anti-dandruff function has no effect on scalp, so it is unnecessary to apply it on scalp deliberately. However, the conditioner with anti-dandruff function must be in contact with the scalp to exert its anti-dandruff effect, so it should be applied to the scalp.
